Description
Electric central locking lock for the right front (passenger) door of the Citroën C4 Coupé, first series.
Product Overview
This is a used central locking door lock/actuator intended for the right front (passenger) door of the Citroën C4 Coupé (first series). The unit is compatible with vehicles using the listed part numbers and is a direct replacement for failed or worn door locks. Ideal for professional mechanics and experienced DIY technicians seeking an OEM-fit solution to restore reliable central locking operation.
Key Features and Function
- Restores Central Locking: Controls the mechanical latch and electric locking/unlocking of the right front door via the vehicle’s central locking system.
- OEM Fitment: Matches original mounting points and linkage for straightforward replacement on compatible Citroën C4 Coupé models.
- Common Symptoms Indicating Failure: Door that will not lock/unlock with remote or central locking, intermittent operation, audible motor noise without movement, or door not latching securely.
Typical Causes Of Failure
Door locks commonly fail due to mechanical wear of internal gears and levers, corrosion from moisture ingress, broken or fatigued plastic components, seized linkages, or wear in the electric actuator motor. Water ingress and accumulation of dirt inside the door cavity accelerate wear and corrosion, especially in older vehicles or cars exposed to harsh climates.
Replacement And Installation
Replacement requires removal of the inner door trim panel to access the lock assembly. Typical steps:
- Disconnect Battery Before Work: Always isolate the vehicle battery before starting to avoid short circuits and potential module damage.
- Remove Door Trim And Moisture Barrier: Carefully detach trim clips and the water shield to access the lock and linkage.
- Disconnect Electrical Connector And Linkages: Label or note the positions of rods and cables before detaching to ensure correct reassembly.
- Unbolt And Replace Lock Assembly: Remove retaining bolts, fit the replacement lock, reconnect linkages and connector, then test operation before reassembling the door card.
- Functional Check: Verify locking/unlocking by remote and interior switch, and confirm the door latches and opens smoothly.
Installation Recommendations
- Use Appropriate Tools: Use trim tools to avoid damaging the door card and correct-size sockets for bolts.
- Inspect Linkages And Clips: Replace brittle or corroded rods, clips, and grommets to prevent premature failure after installation.
- Protect Against Moisture: Ensure the moisture barrier is reinstalled correctly; apply dielectric grease to electrical connectors to reduce corrosion risk.
- Test Before Final Assembly: Operate the lock multiple times and confirm mechanical engagement before refitting the door trim.
